To all io/tom t may concern.' g

Be it known that I, ALDEN L. PUTNAM, a citizen of the United States of America, residino' at Detroit, in the county of lVayne and State of .llfiichigam have invented certain new and useful Improvements in Vehicle VVhe'els, of wh the following is a specification, refer. being had therein to the accompanying drawings.

The invention relates tovehicle wheels designed for heavy service, such as on trucks, and it is the object of the invention to facilitate replacement.

In the present state of the art, it is common to provide lighter vehicles, "such as pleasure cars, with demountable rims or depermitting of quick exchange. @n the other hand, with heavy vehicles, which are usually provided with solid tires, demountable rims or demountable wheels Lare seldom, if ever, used. Nevertheless there are occasions when the wheel becomes inoperative and requires either replacement or repair. lVith my invention I have provided a construction which facilitates quick replacement and which comprises essentially twin demountable wheels capable of being mounted or detached as unit. A further feature of the invention is the forming of these twin wheels with dished disk bodies having a cross-section tapering from the point of attachment to the hub to the point of attachment to the rim. One of these disks is arranged to cross the central plane of impact of the wheel, while the other disk is oppositelydished to form a brace for the overhanging portion of the rim. At the hub the disks have parallel portions which are secured to each other and are generally clamped to the hub flange, the detailed confollows tions are secured.

about the flange portion` F. The portions H and E are preferably secured to each other by suitable means, such as the threaded studs J. Each diskis'also preferably formed of metal of tapering cross-section, being of greatest gauge at the center and diminishing towards the periphery. At the periphery is a portion K preferably lying parallel to the portions E and H and to which the rim secvThese rim sections are formed in pairs which are respectively se` cured to the disks D and G. The sections M and M are arranged on opposite sides of the 'center of the wheel and between the portions IS of the two disks, while the sections N and NV are arranged outside of the d .sk All of these sections are secured in posit-ion, preferably by clamping-bolts '0, which )ass through the flanges of the sections M it" N and N andthe portions K of the disks G and D, while at the outer ends of said bolts are the clamping nuts I). Thus when the nuts are tightened, the sections M and M are clamped against eachother and the sections N and N and disks G and D are clamped/,the sections N and N forming a rigidly braced structure. The tires Q aie mounted on the rims in any suitable manner, preferably by providing each with a band R- which is pressed upon the rim sections.

For demountably supporting the wheel from the hub studs S are secured to the ange A, each of said studs having a portion rI for engaging a corresponding aper ture in the portions H and E of the disks G and D. I] is a clamping ring for bearing against the outer face of the portion H, being preferably provided with the wedge portion V for engaging a cooperating wedge portion on the Iange I. W is a clamping ving a bearing thereon. G

Figure l is a section through the wheel;

Figure 2 is' a side-elevation through a segment of the wheel.

A is the hub of a vehicle wheel, A is the flange thereof and B is the brake-fiange secured to said iiange by suitable means, such as the bolts C. l) is a dished disk having a portionyE which lies parallel to the flange A', said disk being apertured to tover the hub and having a cylindrical iiange F formis a second disk nut for engaging the threaded outer end of the stud S, said nut being preferably provided with an extension sleeve X which telescopically engages the stud and the aperture in thering so as to permit of separately unscrewing.

ll'7 ith the constructiondescribed the several parts of the wheel can be readily formed of pressed sheet-metal and easily assembled in relation to each other. The complete structure is one possessing a high degree of strength and rigidity while the weight is relatively small.

having a portionA II `fit-ting against the porlifhat I claim as m-y invention is: tion E and a. frange portion I which fits i. vehicle wheel, comprising a pair of il@ j dished disks having their central portions lying adjacent to each other and their peiipheralk iortions Haring oppositely, a rim formed oi a plurality of sections secured to said disks, a pair of said sections being arranged between said disks and abutting against each other, a pair of'sections arrangedvoutside of said disks, and clamping bolts passing through said sections and disks and securing the same to each other.

2. A vehicle wheel, comprising a pair 0fdished disks ofltapering cross-section,the central portions of -said disks lying in parallel adjacent planes and being secured to each other, the peripheral portions lying in parallel planes and fiaring portions arranged intermediate said central and peripheral portions, a rim formed of a plurality of sections secured to said disks, a pair of said sections being arranged between said disks, a pair arranged on opposite sides of said dlsks, clamping bolts passing through said sections and disks for securing the same-to each other, and means for demountably securing hebcentral portions of said disks to the axle iu i 3. A vehicle wheel, comprising a dishedl disk of tapering cross-section having its central portion arranged on one side of the plane of impact of said disk and its peripheral por.- tion arranged on the opposite side thereof, a second oppositely-dish-ed disk having its eentral portion lying adjacent to tlie first-mentioned disk and its peripheral portion spaced therefrom, a rim formed of a plurality of sections, a pair of said sections being arranged between the peripheries of said.

pair being ardished disks, a cooperating' each of said ranged outside 'of said disks,

sections havingan inwardly-extending flange a lying adjacent to one of said disks, and clamping bolts extending through the flanges of said sections and theperip-heral .portions of said disks for securing the same to each other. j j 4. A vehicle wheel comprisingbodies hav- `ing their central portions in proximity and diverged outwardly from said portions, .a

rim formed of a plurality of sections, a pair of said sections being arranged between the peripheries of said bodies, a cooperating pair A -their inner portions lying adjacent to each other and their peripheral portions flaring oppositely, a rim comprising a lflanged section between the disks and flanged sections outside of the disks, and,l clamping bolts ex tending through the fianges of said sections and through the peripheral portions of the disks for securing the'same to each other.
